| distance / time | formula for speed |
| velocity | speed in a certain direction |
| acceleration | when an object speeds up, slows down, or turns |
| example of speed | 70 mph |
| example of velocity | 30 mph west |
position-time graph,  | constant speed moving away |
velocity-time graph,  | moving toward to begin with |
position-time graph,  | stopped to begin with |
| Speed if running 12 miles in 2 hours? | 6 miles/hour |
| Velocity if running 12 miles west in 2 hours. | 6 miles/hour west |
| Speed if driving 120 meters in 20 seconds | 6 meters/second |
| Velocity if driving 120 meters in 20 seconds to the right | 6 meters/second right |
| Resultant velocity if an escalator is moving 2 m/s up and you walk on it 3 m/s up | 5 m/s up |
| Resultant velocity if an escalator is moving 2 m/s up and you walk on it 3 m/s down | 1 m/s down |
| Resultant velocity if treadmill is going 4 mph backward and you walk 4 mph forward | 0 mph |
